To (ZZZ whom it may concern Be it known that 1, JOHN H. Kinrrnn, acitizen of the United States, residing at Allentowi'i, in the county ofLehigh and State of Pennsylvania, have invented a new and useful.Toe-Calk, of which the following is a specification.

The present invention ap pertains to horseshoe (fillkS, and moreparticularly to toe calks.

It is the object ot the present invention to provide a toe callr forhorseshoes, which shall. he comparatively simple, nou-encunibering andinexpensive in construction, which shall be of such construction, as tobe readily applicable to and removable from the toe oi a horseshoe,which shall he capable of withstanding the hard usage and strains towhich it is subjected. when in use, and which will otherwise be ofadvantage in its use.

With the t'mregoing and other objects in view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed, can he made within thescope of what is claimed, without departing from the spirit oi theinvention.

The invention. has been illustrated in its preferred embodiment in the a1conn anying drawing, wherein Figure l is a bottom view of a horseshoehaving the improved toe calk applied there to. Fig. 2 is a sectio atview taken on the .line 22 of Fig. 1. Figs. 3 and 4- are sectional viewstaken on the lines and 4t-l-, respectively, of Fig. 2.

In the drawing, the numeral 1 designates an ordinary horseshoe, and thenumeral. 2, designates generally, the improved toe calk.

The toe calk is constructed of hardened steel, or other suitablematerial, capable of withstanding wear and tear to a high degree. Thetoe call: 2 is disposed transversely across the bottom of the horseshoe,at the toe thereof, and the call: 2 is divided in termediate its ends bya diagonal cut 3, to provide two end sections t and 5. respectively. Theadjacent or meeting ends ot the calk sections 4 and 5 are beveled or outchliquely, so as to overlap or tit snugly together, when the call:sections are alined,

the remote or outer ends oil? the ealh' sections being rounded or cut soas to conform to the outer edges oil. the horseshoe. The forward side otthe call: is flat, and perpendicular to th e horseshoe. while the rearside or face of the calk is pre ably inclined or beveled, from the freeor lower edge of the talk, to pro vide a sharp anti-slipping edge.

To attach the calk sections l and 5 to the horseslme, the toe portion oithe horseshoe providml with laterally arranged or spaced threaded bores(S, which. are provided. at their lower ends with enlarged counterhoresor sockets '1'. Each of the call: sections is provided at its upper edgeor basal por' n, and. intermediate its ends, with a boss 8 adapted tofit snugly within. one oi? the eouuterljiores 7. the boss 8 beingprovided with a threaded projection 9 engageable in the correspondingbore (3 ot the horseshoe. Ordinarilv, when. the call: is in place, thebosses or studs 8 snugly engage the coimterbores 7, while the threadedprojections or stenu; tl threadedly engage the bores (3, to maintain thecall: sections firmly in position.

In order to clamp or secure the .tllk sections together, the adjacentends of the call; sections are provided upon their rear side with a.boss 10, which is disposed adjacent the horseshoe 1, and which isdivided by the cut 3, the inner end of the calk section 5 carrying thegreater portion of the divided boss 10. he adjacent ends of the calksections are also provided with a bore or opening 11 adjacent thehorseshoe, or the basal portions oi? the call; sections, the bore 11being coaxial with the boss 10. The forward end of the bore 11 extendsthrough the inner end of the calk section t, while the rear end of thebore extends through the main portion of the boss 10 forming a portionof the inner end of the callt section It may thus be said that the boreor opening 11 passes through the overlapping or meeting end portions ofthe call: sections.

To clamp the adjacent ends of the call: sections firmly together, a bolt12 is passed through the here or opening ll. the bolt being providedwith an elongated head 15:3 at its forward end engaging the forward sideof the calk section 4-, and overlapping the forward side oi the calksection the bolt head 13 resting snugly against the bottom of thehorseshoe. A clamping or retaining nut 14: is threaded upon the rear endof the bolt 12, and a nut-locking washer l5 sandwiched or disposedbetween the nut 1d and the boss 10, the split washer and nut 14: seatingagainst the boss 10 of the call; section 5, and slightly overlapping therear face or side of that portion of the boss 10 carried by the innerend of the calk section Thus, when the nut 1 L is tightened, theadjacent ends of the calk sections will be tightly clamped together, inorder that the call: sections will present a substantial uni tary call:construction.

In applying the toe call: to a horseshoe, after the threaded bores andcounterbores 6 and 7, respectively, have been applied in the toe portionof the horseshoe, one of the calk sections st is threaded in engagementwith the corresponding bore 6, and when the said call: section has beencompletely engaged to the horseshoe, the same is reversed for av quarterof a turn, so as to assume a longitudinal position. The other call:section is then threaded in engagement wit-h the corresponding bore 6 ofthe horseshoe. Then, when the last mentioned call: section approachesits normal or final position, both of the calk sections are turned sothat the inner ends of the call: sections overlap or abut, when thecall; sections are brought into alinement. It is to be noted that thescrew threads of the bores 6 and threaded stems or shanks 9 are all inthe same direction, whereby the calk sections will rotate in the samedirection when being threaded into engagement with the horseshoe, and inorder that the inner or beveled ends of the calk sections will swingtogether or meet properly. After the call: sections have thus beenapplied, the clamping bolt 12 is engaged through the bore 11. After thebolt has been inserted through the bore 11, the washer 15 and nut 1a areapplied to the bolt, and when the nut is tightened the call: sectionswill be firmly clamped together. The toe call: thus presents asubstantial antislipping device for the shoe.

The bosses S engaging the counterbores 7, are of advantage, inasmuch asit is possible. in practice. that the screw threads will not permit thecall: sections to aline at the same moment that the call: sections seatagainst the horseshoe. which would necessitate a slight unscrewing ofthe calk sections, which would be objectionable. ith the provision ofthe bosses S and counterbores 7, however, the bosses S in engagingwithin the counterbores will take up the strains in an effective manner.notwithstanding the fact that the calk sections are slightly unscrewedwhen in normal position. Furthermore, the bosses in fitting snuglywithin. the counterbores 7 of the horseshoe, will also relieve the screwthreads of considerable strain, as when the i call; is subjected tostrains approximately parallel with the horseshoe.

The present call: may be readily applied to and removed from thehorseshoe, as is ob vious from the foregoing, and is of advantage inother obvious respects, it being noted that the objects aimed at havebeen carried out satisfactorily. If desired, the toe calk may be prvided with a blunt edge, instead of a sharp one.

Having thus described the invention, what is claimed as new is 1. A toecall; having a diagonal cut intermediate its ends dividing it into twosections, the call: sections having threaded projections at their basalport-ions and intermediate their ends, the meeting ends of the call:sections having a bore therethrough, one end of the bore extendingthrough the corresponding end of one calk section, and the other end ofthe bore extending through the corresponding end of the other call:section. a bolt extending through the said bore and having a head at oneend seating against one side of one call: section and overlapping thecorresponding side of the other call: section, and a nut engaged to theother end of the bolt and seating against the other side of one call;section and overlapping the corresponding side of the other calksection.

2. A toe call: having its rear side inclined from the free edge of thecalk, the rear side of the call; having boss at the basal portion of thecalk, the call; and its boss, being divided on a diagonal line,intermediate its ends, to provide two alining sections, the call:sections having threaded projections at their basal portions andintermediate their ends, the adjacent ends of the call: sections havinga bore therethrough coaxial with the said boss, the bore being disposedadjacent the basal portions of the call: sections, one end of the boreextending through the corresponding end of one call: section, and theother end of the bore extending through the corresponding end of theother calk section, a bolt fitting through the said bore and having anelongated head at its forward end seating against the forward side ofone call: section and overlapping the forward side of the othercallzsection. and a nut threaded upon the rear end of the bolt andseating against the boss sections of the two call; sections.

In testimony that I claim the foregoing as my own, I have hereto affixedmy signature in the presence of two witnesses.
